Kelly Osbourne Shares Sweet Photos with Son Sidney on Mother's Day: 'Single Best Thing to Ever Happen to Me'

Kelly Osbourne is cherishing her family on Mother's Day.

On Sunday, Osbourne, 39, shared a heartwarming Instagram carousel of photos featuring her and her 18-month-old son Sidney, whom she welcomed with her partner Sid Wilson in November 2022.

In the first photo, Osbourne smiles at the camera while cradling her son in her arms. The following picture captures Sidney's attempt to put a pacifier in his mouth. In the last photo, Sidney is pictured solo, facing the camera with the pacifier in his mouth.

"I love nothing more than being your mother! You are the single best thing to ever happen to me. Thank you for being my baby!" Osbourne captioned the post.

Earlier this month Osbourne spoke to PEOPLE about Osbourne Media House and The Osbournes Podcast, and revealed more about managing her health while pregnant.

“I didn't get to have the pregnancy where you eat whatever you want. It sucked. I was hungry for nine months,” the mom of one said. 

During the interview, she revealed she developed gestational diabetes during pregnancy, prompting her to adhere to a "completely sugar-free diet and avoid carbohydrates" to prevent the condition from persisting after childbirth.

“It really scared me,” she added. “ I didn't want to deal with any of that.”

Back in March, Osbourne shared a sweet Instagram Reel of her, Wilson and their son during their family's Easter egg hunt.

"Happy Easter 🐣 EVERYONE!!! We had the best time at @danikid Easter egg hunt! Seeing how exacted baby Sid was collecting all his eggs warmed my soul! 🪺," she captioned her post. .
